Khloe Kardashian admitted she "knocked out" one of her brother Rob Kardashian's teeth.

The reality star recalled a story involving her younger brother, in which a play fight turned nasty.

Khloe, who recently gave birth to her daughter True, revealed she Rob had a fight in a car for an hour and a half and she hit him so hard she knocked out his tooth.

The new mother added there was blood everywhere and admitted it was quite the car ride for their Dad’s friend, who was the driver.
